How to differentiate parent and child node in af:treeTable ?

Greetings,
I have a requirement, I display master child view objects using <af:treeTable> component, When user expands a parent row, I have to make parent row is in read only and expanded(child) row in editable. To accomplish this I have to identify the 'node' whether it belongs to parent or child view object. In this example Tree table binds with EmpVO, There is a view link beteween EmpVO and DepartmentVO.
<af:treeTable value="#{bindings.EmpVO.treeModel}"
var="node"
rowSelection="single" id="tEqSum"
summary="Employee Summary"
<af:column sortProperty="#{bindings.EmpVO.hints.LocCity.name}"
filterable="true" sortable="true" width="90"
headerText="#{bindings.EmpVO.hints.LocCity.label}"
id="c3">
<af:outputText value="#{node.LocCity}" id="ot21"/>
expandAllEnabled="false">
</af:treeTable>
Thanks in Advance,

Hi,
You can find out the node depth by using
#{bindings.<your_tree_binding>.treeModel.depth}Based on the depth, you can decide whether its a parent node or child node (for a 1 level tree- say dept and emp, the depth for parent would be 0 and for the child it would be 1).

How to link parent and child relation in Metapedia

Vamsi,
Did you every determine how to do what you were asking about? Where you thinking of how to link a parent term to a child term (i.e. like a related term) or was this about linking a term to a different metadata object (e.g. table or report) ?

How to update parent and child tables while updating parent table

I have a parent table EMPLOYEE which includes columns (sysid, serviceno,employeename...) sysid is Primary key, serviceno is Unique key and I have child table DEPENDENT includes columns (sysid,employee_sysid,name,dob...) here again SYSID is primary key for DEPENDENTS table, employee_sysid is Foreign key of EMPLOYEE table.
Now I want to change SYSID (using sequence) in EMPLOYEE table which need to be update in DEPENDENTS table as well
Note: I have 10000 records in EMPLOYEE table as well as I have 5 more child tables which need to update new SYSID.
please help me

first disable the FOREIGN KEY Constraints.
you can update Parent as well as Child record also with help of trigger.
here i am giving you one examlpe..it may help u.
create table parent(id number primary key,name varchar2(100))
create table child_1(id number primary key,p_id number,dob date,
CONSTRAINT FK_id FOREIGN KEY (p_id) REFERENCES parent (ID))
create table child_2(id number primary key,p_id2 number,addr varchar2(1000),
CONSTRAINT FK_id2 FOREIGN KEY (p_id2) REFERENCES parent (ID))
insert some test data to parent and child tables.
alter table child_2 disable constraint FK_id2
alter table child_1 disable constraint FK_id2
CREATE OR REPLACE TRIGGER delete_child
BEFORE UPDATE ON parent
FOR EACH ROW
BEGIN
UPDATE CHILD_1
SET P_ID=:NEW.ID
WHERE P_ID=:OLD.ID;
UPDATE CHILD_2
SET P_ID2 =:NEW.ID
WHERE P_ID2=:OLD.ID;
END;
then Upadte parent table primary key col and check the child tables.
then enable the constraints...

How to persist parent and child tree node data through JSF and Hibernate

Dear dudes,
I'm a novice to JSF and Hibernate
Actually i want to create a tree structure where for each child node, i should have the parent node reference in my form and then when i save, i need to save the corresponding child node data in the database.
node-1
node 1-1
     node 1-11a
node 1-2
node-2
   node 2-1
   node2-2Whenever i click node 1-1 the corresponding parent node ( node-1) reference should appear in my form and when i save this data this data should be saved under parent node and the tree should be re-rendered.
How this can be accomplished and if there are any URL's please refer.

How to delete parent and child records together ?

Hi,
I'm using Jdeveloper 11.1.2.2
I want to delete a row from a table but it is showing: Caused by: java.sql.SQLIntegrityConstraintViolationException: ORA-02292: integrity constraint (TABLE1_TL_FK1) violated - child record found.So how can I delete a Child row and table row in one method ?
I cannot access the child's VO because it is not added to the AM.
Thanks,
Nigel.

John, as usually, is right with the pointer to the documentation he pasted. Just to make sure you read it carefully, let me hoghlight an important point here:
"If the option is selected, then the composed entities do not perform the DELETE statement *on the assumption that the database ON DELETE CASCADE constraint will handle the deletion of the corresponding rows*."
So make sure the database is setup for cascade delete as otherwise you still will not succeed

How to delete parent and child records?

Hi friends,
I have a Master table and a child table.
The Child table got reference key with the master table without on delete cascade.
Now, I want to delete the Master records and also it's corresponding child records.
How to do?
Thanks in adv,
regards,
Vijay

Delete the records from the child, then delete the records from the parent in two separate delete statements. I'd prefer that you create a stored procedure that does both steps.

Problem while handling Parent and child nodes in CE

Hi all
I am facing a problem with handling Child and Parent nodes in CE.
I have a Table in which I have drop downs. On selecting a value in the drop down, I have to take that value and do some action.
I am trying to access the value in the following ways
wdContext.nodeParent().currentParentElement().nodeChild().currentChildElement().getVaActivity();
wdContext.nodeChild ().currentChildElement().getVaActivity();
When I select the drop down from the first row of the Table the code works fine.
But when I select other rows, it returns the current value of the first row.
The lead selection of the parent always returns u20180u2019 even though you have done some action in row 2,3 etc.
The same code gives the required values in EP 7.0; I.e.: it returns the values form selected row in the table.
Basic problem is that the current value of parent always returns the first row.
Following are the Properties of the nodes
Parent
Collection Cardinality: 0-n
Singletone: true
Child:
Collection Cardinality: 0-n
Singletone: false
Please help
Regards
Deepu

Hi,
   In CE changing dropdown selections doesn't fire table leadselection events. If you want to use a dropdown in a context-driven UI element like a Table, you need to use of event parameter mappings. So here are the steps:
1. Create a new action for the onSelect event of the dropdown (I will write the code for DropDownByIndex), let's call it Select.
2. Add a parameter parentElement whose type is same as the type of the parent node element. So from your example it would be IParentElement. Select the chek-box for "Adapt event-handler parameter". This will add a new parameter to the event-handler method onActionSelect called parentElement.
3. Write this inside wdDoModifyView :
if (firstTime) {
    IWDAbstractDropDownByIndex ddi = (IWDAbstractDropDownByIndex) view.getElement("<id of DropDownByIndex>");
    ddi.mappingOfOnSelect().addSourceMapping(IWDAbstractDropDownByIndex.IWDOnSelect.NODE_ELEMENT,"parentElement");
3. If you want to set the lead selection of the table to the row where the dropdown is write this inside the event-handler:
wdContext.nodeParent().setLeadSelection(parentElement.index()); //parentElement is the event handler parameter added through the action.
Note that the event parameter IWDOnSelect.NODE_ELEMENT points to the node element that defines the data mapping for the containing row and not the node element of the source for the dropdown. This has been specfically added for such a scenario. All this is well documented [here|http://help.sap.com/javadocs/nwce/current/wdr/com/sap/tc/webdynpro/clientserver/uielib/standard/api/IWDAbstractDropDownByIndex.IWDOnSelect.html#NODE_ELEMENT].

How to filter parent and child tables data in impdp?

Hi Friends,
i hope everyone doing good..
I have two tables in my schema like below.
STUDENT_DTLS:-
SID Sname CID
1     venkat     001
2     uppy     002
3     deepu     003
4     trinath     003
5     naveen     004
6     ramesh     005
COURSE_DTLS:-
CID CNAME Fee
001     Oracle     2000
002     java     6000
003     sieble     4000
004     informatica     3000
005     obiee 4000
if I load only few Student details say sid=1,2,3 into another environment using impdp,corresponding to those students course details from COURSE_DTLS table only need to be loaded.Not all course details.
Iam Expecting Result in new schema as below:-
SID Sname CID
1     venkat     001
2     uppy     002
3     deepu     003
CID CNAME Fee
001     Oracle     2000
002     java     6000
003     sieble     4000
But when i am using the below import scrit,The COURSE_DTLS is loading first and its query option(select cid from STUDENT_DTLS) is returning no rows.Because at that time no data is insertred into STUDENT_DTLS yet.
secondly it is importing data into STUDENT_DTLS with query option where sid=in (1,2,3) which is loaded propelry.
Thirdly it is trying to enable primary key and Foreign key constraints which is also failing because of no data in COURSE_DTLS table.
i have changed the order of tables in TABLES clause like tables=COURSE_DTLS ,STUDENT_DTLS.But still COURSE_DTLS table is loading first.
impdp pa_data_sub/******* NETWORK_LINK=qdssih30 tables=STUDENT_DTLS,COURSE_DTLS query='STUDENT_DTLS:"where SID IN(1,2,3)"','COURSE_DTLS:"where cid in(select cid from STUDENT_DTLS)"', CONTENT=all table_exists_action=replace directory=DATA_PUMP_DIR logfile=exp_join.log

Failing sql is:

Processing object type TABLE_EXPORT/TABLE/STATISTICS/TABLE_STATISTICS
Job "PA_DATA_SUB"."SYS_IMPORT_TABLE_01" completed with 1 error(s) at 17:28:13
Please suggest me how to achieve this task in a single import command?
Is there any option in impdp to prioritize the table to be loaded first?
Thanks,
Venkat Vadlamudi

You can't be guaranteed which order the data will be loaded in, so using a query that examines a table that is being imported is not going to always work the way you want it. The failing constraints makes sense because there is no data.
So, in your case, course_dtls gets imported first and the table student-dtls exists, but it not populated yet, so the select cid from student_dtls comes back with 0 rows. The second query works fine.
You might be able to change the query to be:
'COURSE_DTLS:"where cid in(select cid from STUDENT_DTLS@qdssih30 where SID IN(1,2,3)"'
This way, you query the source table pointed to by the network link and you use the same subquery from the first table.
This should work for you... I think anyway.

Hi,
you need to provide the full naming for the facet names. So instead of DepartmentsView you provide mypackage.DepartmentsView where you replace mypackage with the package structure of the the ViewObject

How to create parent and chile process in java

i'm beginning in java, and i want to ask something, please help me...
1. i want to ask how to create parent and child process in java???
example :
if have one window and explore menu, when i click the explore menu.
new window come out.
how if i close the parent window the child window will close too...
2. what is the method from runtime class to get available memory and Active Threads count

ONE way to do what you wanted is this.
class Parent{
Child c = new Child
allChildren.add(c);
//if close
iterate through list
(Child)allChildren.get(index).close();
ArrayList allChildren;
class Child{
public void close(){ }
i dont know if you can get the thread count. but you can
get the current thread by using System.
Memory: Runtime.freeMemory() .maxMemory() .totalMemory()
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html
Careful though you have to do a calculation to get the
actual memory because those 3 methods refer to freeMemory
of the CURRENT heap not the total memory.
i think its: total - (max - free)

How to differentiate between Parent and Child in IBASE?

Hi. I am working on enhancing a BAPI :BAPI_GOODSMVT_CREATE by calling the following function module IBPP_CREATE_IBASE at its exit.
The BAPI is being called from an SAP ME system and will be passing MATNR and Serial Number of Parent and Child materials to create the IBASE in ECC system. I am confused as to how to differentiate between whether a object is Parent or a Child when the BAPI: BAPI_GOODSMVT_CREATE is called.

if you have NULL valued fields. If
you do a compare and one or both are NULL, then the result is always NULL,
never true or false. Even comparing two fields which are both NULL will
give NULL as result, not true! Or if you have something like "select
sum(field) from ..." and one or more are NULL, then the result will be
NULL. Use always "if field is NULL ..." for NULL checking and for safety
maybe something like "select sum( IsNull(field,0) ) from ...". Check the
function ISNULL() in the manual.

Hi PanosE,
Yes, you can set up another Standard Edition Server in child domain and then deploy pool pairing.
You need to deploy a new Front End Pool for the new Standard Edition Server.
A similar case for your reference.
